UPSC Prelims 2023 Question:

Wolbachia method is sometimes talked about with reference to which one of the following?

1. Controlling the viral diseases spread by mosquitoes
2. Converting crop residues into packing material
3. Producing biodegradable plastics
4. Producing biochar from thermochemical conversion of biomass

Answer (Detailed Solution Below)

Option 1: Controlling the viral diseases spread by mosquitoes

Detailed Solution

Explanation:

The Wolbachia method is simple. when Aedes aegypti mosquitoes carry Wolbachia, the bacteria compete with viruses like dengue, Zika, chikungunya and yellow fever. This makes it harder for viruses to reproduce inside the mosquitoes. And the mosquitoes are much less likely to spread viruses from person to person. This means that when Aedes aegypti mosquitoes carry natural Wolbachia bacteria, the transmission of viruses like dengue, Zika, chikungunya and yellow fever is reduced.

Therefore, option (1) is the correct answer.
